2. In a mine-car, the floor thereof having bottom openings closed on allsides, and a truck having integral projections adapted to enter and beembraced on all sides by the openings.

3. In a mine-car, the floor thereof having laterally-inclosed bottomopenings, a truck having apertured projections adapted to enter and beembraced on all sides by the openings, and securing-bolts extendingthrough the floor and the apertured projections.

4:. In a mine-car, the floor thereof having bottom openings closed onall sides, axle-boxes having integral projections on their upper sidesadapted to enter and be embraced on all sides by the openings, and meansfor securing the boxes.

' 5. A mine-car having angle-bars traversing the bottom thereof,axle-securing devices fitting the angles of the bars and projecting overthe latter, and a connection between the projecting portions of saiddevices and the carbottom.

6. A mine-car having angle-bars traversing the bottom thereof,axle-securing devices litting the bars and projecting beyond the opensides of the latter, and projections on said devices adapted to enterdepressions in the carbottom.

7. A mine-car having angle-bars traversing the bottom thereof,axle-securing devices fitting the angle-bars and wider than the latter,apertured projections on the upper sides of said devices, and securingbolts extending through the car-bottom and said apertures.

8. A mine-car having angle-bars traversing the bottom thereof andarranged back to back, a cross connection between the backs of saidbars, axle-securing devices fitting the anglebars, and axles.

9. In a mine-car having angle-bars traversing the bottom thereof andarranged back to back, straps connecting the backs of the bars, boltsfor maintaining saidconnectiomand axlesecuring devices fitting theangle-bars and formed with depressions to embrace the heads of saidbolts.

10. A mine-car having bars traversing the under side thereof,axle-holding devices secured to and projecting beyond said bars. andinterlocking connections between the projecting portions of said devicesand the car-bottom.

11. A mine-car having angle-bars traversing the bottom thereof andarranged back to back, connecting-straps interposed between the barbacksand having their ends turned downward, bolts extending through thebar-backs and the turned extremities of said straps with the boltnutsfitting the angles formed by the bends of said straps, and axle-boxesfitting the anglebars and formed with depressions to receive the headsof said bolts.

In testimony whereof I aflix my signature in presence of two witnesses.
